ing at the problem that the existing person re-identification algorithm cannot be adapted well to the variances of illumination, attitude and occlusion, a novel person re-identification algorithm based on feature fusion and subspace learning is proposed, in which the Histogram of Oriented Gradient (HOG) feature and the Hue-Saturation-Value (HSV) histogram feature are first extracted from the entire pedestrian image as the overall feature and then the Color Naming (CN) feature and the two-scale Scale Invariant Local Ternary Pattern (SILTP) feature are extracted in a sliding window. In addition, in order to make this algorithm have better scale invariance, the original images are first down-sampled twice and then the above features are extracted from the sampled images. After the features are extracted, a kernel function is used to transform the original feature space into a nonlinear space, in which a subspace is learned. Simultaneously, in this subspace, a similarity function is learned. The experiments on three public datasets are conducted and the results show that the proposed algorithm can be used to improve the re-identification rate relatively well.
